New owner - oil question, cant find answer
Hey guys, I recently bought an 05 Rx-8. It seems that the oil was last changed with 10w30 oil. According to you guys and the manual, this car wants 5w30/20 if im not mistaken. Should I be worried? Also, if i were to "top up" the oil in between oil changes, should the oil match the oil already present in the car in terms of brand, type(5w30/5w20), etc? Oh yeah, I am an AZ resident....not sure if that justifies the 10w30.....
Thanks for any help,

Hey welcome to the forum! I'm sure you'll enjoy the car and the social club that goes with it. You're okay with the 10W30 oil but if it worries you then take it back and get it changed out. If you run 10W30 I'd top up with the same until your next change.
What's the weather like this time of year? It's snowing a bit today up here...

I guess thicker oil would be adequate for intense summer heat, then change it back to 5w20 during colder temperatures. Keep using the same weight if you want, the brand I don't think matters. Normally high mileage would require thicker oil. I recently changed all my fluids to Royal purple and I'm not getting the funny smell some people are experiencing in the forum Good luck

5w30 10w30 should be fine in your climate. Not as hot in Ga as it is an Az, but hardly ever "really cold"
As for matching the weights/brands - shouldn't have to worry about it. If you have 10/30 and want to run 5/30 - starting adding 5/30 if you need oil and have it changed to that next change.

I know Valvoline pushes their "old car" blend for high mileage vehicles, but that seems to have additives that swell gaskets to prevent leaks, rather than the old STP-type thickeners that might help worn oil rings.

Temp is not as important as the fact that your car burns oil by design. ( think oil injected 2 stroke as an example ) 5w20 burns really clean, so that is what I use.
Or just premix if you want <--- search for it. Lots of opinions on that topic

If I lived in a hot climate, I would make sure to use 5W-30. I use it now and I live in coastal California where it doesn't really ever get too hot.
I am not too picky about the oil I put in my car as long as its dino oil and it meets all the highest standards. I change my oil out every 3K miles so it doesn't stay in that long.
